BACKGROUND: Rapid tuberculosis (TB) diagnostics are essential for TB control.
Factors influencing the uptake of these technologies in Africa are not
well-documented for all technologies and are completely undocumented for some
countries. We conducted a survey to collect the status and document Predisposing,
Enabling, and Need (PEN) factors influencing uptake so that we understand the
associated barriers and inform interventions to improve the uptake. METHODS: We
designed, piloted, and distributed a survey questionnaire in January 2023 to the
National TB Programme (NTP) and National TB Reference Laboratory (NTRL) managers
as well as key partners of the Ministry of Health in the 47 Member States of the
World Health Organization African Region (WHO/AFR). Responses were accepted until
July 2023. We performed quantitative data analysis using STATA version 14.0.
RESULTS: From the 47 eligible countries, 22 responses (47%) were received from
the NTRL managers, 17 (36%) from Technical Assistants (TAs) for NTRL and NTP, and
8 (17%) from the NTP managers. Our findings showed that it took between two to
nine years from the endorsement of a new technology to its full implementation,
with the duration increasing with the complexity of the test. Laboratory
preparedness, staff competence, and policy reform were the main predisposing
factors; availability of funds was the primary enabling factor, whereas the
emergence of MDR-TB was the key need factor. Good governance and political
commitment aligned with the existence of the Directorate of Laboratory Services
and the NTRL, were crucial facilitators driving the adoption, adaptation, and
implementation. CONCLUSION: Our findings demonstrated that the uptake of TB
diagnostics in Africa is slow. Considering the laboratory preparedness, staff
competence, policy reform, availability of funds, and the emergence of MDR-TB as
the main PEN factors identified could help speed up the uptake and rapid
implementation of any new technology.
